Information on the security status of a VTS-TSR, like whether it is SAF interface protected, hardware key protected, in read-write or read-only mode as well as its generation number can be found in the parameter, VTS-DATA. This parameter is retrieved using the LV command by providing the VTS name in the TB-SUBSYSTEM field of the TB-PARM parameter.
For more information on VTS-DATA and the LV command, please refer to the tableBASE Programming Guide.
